Let's divide 28033391 by 230
The aim is to understand the frequency of 230 in 28033391.

On to step 1:
The number 230 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 230

On to step 2:
230 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 230

Going ahead to step 3:
280 divided by 230 is 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 230 from 280, we get 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 230

Step 4:
If we divide 503 by 230, we get 2 and a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 460 from 503 leaves us with 43.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 230

On to step 5:
The number 230 fits into 433 1 times, leaving a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtract 230 from 433 to get 203.
Bring next digit (3) of the dividend behind the 203 and repeat the process: 2033 / 230

Let's proceed to step 6:
2033 divided by 230 is 8 with a remainder of 193.
The number 8 becomes the next digit in our result. 
Result so far: 1218.0
If we subtract 1840 from 2033, we get 193.
Bring next digit (9) of the dividend behind the 193 and repeat the process: 1939 / 230

Advancing to step 7:
When dividing 1939 by 230, we get 8 with a remainder of 99.
The number 8 becomes the next digit in our result. 
Result so far: 12188.0
Subtract 1840 from 1939 to get 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 230

Going ahead to step 8:
If we divide 991 by 230, we get 4 and a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 121884.0
The remainder is 71 after subtracting 920 from 991.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
710 divided by 230 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 121884.3
If we subtract 690 from 710, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
If we divide 200 by 230, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 121884.3
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
2000 divided by 230 is 8 with a remainder of 160.
The next digit of our result is 8. 
Result so far: 121884.308
Subtract 1840 from 2000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
When dividing 1600 by 230, we get 6 with a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 121884.3086
Subtracting 1380 from 1600 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 13:
When dividing 2200 by 230, we get 9 with a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 121884.30869
The remainder is 130 after subtracting 2070 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
The number 230 fits into 1300 5 times, leaving a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 121884.308695
Subtract 1150 from 1300 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 15:
If we divide 1500 by 230, we get 6 and a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 121884.3086956
If we subtract 1380 from 1500, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
1200 divided by 230 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 121884.30869565
Subtract 1150 from 1200 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 121884.30869565 and a remainder of 5e-08.
